As an avid paintball player for the last 5 years, and the owner of $550 worth of gear, I'm going to have to vote airsoft.
I've played with some amazing tournament players, and I've played with their equip too.
I'm also going to bodly say that anyone who voted paintball simply doesn't know any better.
Airsoft:
-better accuracy
-further distance
-cooler guns
-cheaper cheaper cheaper to use (ammo, battery, ect, vs co2/no2 + paint)
-no broken balls in barrel
-you don't sound like a candy machine when you run through the woods.
The big detternt for airsoft, and partially why it hasn't caught on is due to it being illegal. Err, the guns that is. You're purchases will be seized at the boarder.
A cop WILL confiscate it on sight, if you aren't shot first.
Don't get me wrong, I love paintball.. but its the clumsy mans game compared to airsoft.
Scenario: You step one step around the corner of a building.
a)Paintball, you can see a ball coming even @ 300+fps, and you dodge it. fine.
b)Airsoft, you're dead.
Oh and Ih8canada, you should make a trip up here so I can kick your Canadian-dissin'-candy-ass.
